COMBINED'GAS AND STEAM ENGINE.

SPECIFICATION forming part of Letters Patent No. 570,263, dated October2'7, 1896.

Application filed August 13,1895- Serial No. 559,160. (No model-) Myinvention relates more specifically to an attachment for gasor vaporengines whereby the motive power is derived from the combustion of gasor vapor, supplemented in a measure by the power of steam obtainedandgenerated directly in the combustion-chamber of the engine by theintroduction of small quantities of water simultaneously with the gas,and whereby the heat generated by the explosion converts the same intosteam and contributes to the motive power of the engine, all as morefully hereinafter described, and shown in the drawing, which representsmy invention in diagram.

A represents the cylinder, B the piston, O

the explosive-chamber, and D the gas-inlet,

all arranged in the usual manner and forming the ordinary parts of agas-engine in which the explosion of the gas or vapor in the chamber 0creates the motive power.

My attachment consists in providing the explosive-chamber with aninduction-pipe E, which is provided with an inwardly-opening check-valveF and opens directly into the offset-pipe or elbow G. Into this elbow oroffset leads a vertical pipe H, leading from a suitable supply-tank I,which is governed by a suitable valve J, all in such manner that a smallstream of water may be allowed to escape through the pipe H and, fiowing through the offset or elbow, may be received and car ried oif by anoverflow K.

In practice my device is designed to operate as follows: Whenever themovement of the piston creates a vacuum in the explosivechamber 0 andthe gas or vaporis introduced into the chamber, the same suction willcreate a draft or air-current to pass in through the offset-pipe andinduction-pipe E and act as a carrier fora small quantity 'of water upfrom the stream of Water escaping. This quantity of water I regulate sothat it will be thoroughly absorbed and converted into steam with eachexplosion of the gas in the cylinder and thereby create a supplementalmotive power.

My device economizes in the use of gas or vapor and by absorbing some ofthe heat prevents overheating and at the same time forms an excellentlubricating device for the piston.

I do not intend to confine myself to any special construction ofintroducing the water at each aspiration of the gas, but theconstruction I have shown I consider to be simple and well adapted forthe purpose.

What I claim as my invention is-- 1. In combination with a cylinder of agas-engine, an attachment comprising an induction-pipe provided with acheck-valve and leading into the cylinder, a verticallydisposedoffset-pipe out of which the induction-pipe leads and having anair-opening therein, means for discharging a liquid into the verticalpipe from a point above theplane of the induction-pipe, and anoverflow-pipe below the offset-pipe, substantially as described. V

2. In a gas-engine, the combination with a cylinder, its piston, and agas-supply leading to the cylinder, of an induction-pipe leading intothe cylinder, a valve therein, a vertical pipe with which theinduction-pipe communicates, having an opening for the admission of air,and means for introducing a liquid into the vertical pipe comprising apipe of a diameter at its discharge less than that of the vertical pipe.

In testimony whereof I affix my signature in presence of two witnesses.
